Yeah, maybe. It's an atypical location, but I know a long absent a2k member who had shingles in her mouth, of all places. I had it once from the center of the back to the sternum. It is horrible.
For what it's worth, a reliable member on another website mentioned olive leaf extract was very helpful with the symptoms. If I had heard about it at the time, I would have ordered some. I repeat that this is not something I have ever used.
